Most of the devices for Washing spinning cakes according to the well known process permit of but a poor production, so that quite a considerable number of such expensive devices are required. Other devices, treatment of cakes in large again, that permit of the quantities, do not always give the desired results, as the cakes are not sufficiently penetrated by the fluids in question. For washing artificial silk in skein form, mechanical devices have been brought out, having a frame with fixed cro ss-rod for the reception of cut skeins, the frame itself being arranged over a trough and fitted lowered. For

for being raised and artificial silk spinning bobbins, too, me-

chanical washing devices are known. The characteristic of these devices spools are placed between is that, the perforated two rotating discs, that are partially immersed in the bath, subjected to vacuum and periodically submitted to the influence of the respective bath.

These devices are, suited for spinning cakes;

however, more or less unthey are either troublesome of service and therefore costly, or the spinning cakes get tangled.

Finally, machines for have made their appearan the treatment of skeins ce, the yarn carriers of which, arranged on both sides, rotate outside the bath above the trough, drawing the skein at the same time through the bath. These machines, too, are but little cakes, as an immersion of bath on these machines is spinning cakes having but suited for spinning the cakes into the scarcely possible, the a small diameter.

The object of this invention is a machine,

which shall treat a large number of cakes at one and the same time, both quickly and efficiently. Which mechanism and cakes being hung on the rods.

frames by means of The cakes may remain in this position during the whole treatment, thus avoiding the disadvantages attendant through the bath.

on On setting the crank mechadrawing the cake nism in motion, the frame together with the spinning cakes is subjected to a circulating motion. The treatment is much more effective, if

the frame with the spinning cakes is lifted out of the bath on every rotation of in this then immersed again;

the crank, and case, a slow revolution of the crank should be chosen, as then the fluid is able to flow to the raised cakes, which a great extent out of take up a fresh quantity of the bath on being reimmersed.

The machine may be c onstructed in double carrier being fitted with crank mechanism and hanging devices to take the frames for the spinning cakes. It will be found expedient to set off the crank mechanism on both sides at 180", in order to provide for a good balancing of the frames. Should only one trough be employed for the double-sided and offset arrangement of the crank mechanism for both frames, it will be found that, on carrying out the treatment by immersion, the further advantage of the bath being thoroughly stirred is obtained, as, on the immersion of each frame, the fluid is driven over to the side then free.

The spinning cakes may be placed on sticks on the frames, not laced and loose. It will, however, be found more effective to place them on holding devices, that are capable of expansion and the circumference of which may be varied, viz. on reels, to provide for a full effect of the fluid on the inner surface of the cake.

If, as is usually the case, several baths are required for the subsequent treatment, several troughs will be placed next to or behind one another; above the troughs there is a track on which the yarn sticks may be run by means of travelling cranes. This track may be endless, so that the yarn sticks may be conveniently brought back to the starting point.

The yarn sticks are brought into position on special stands at the end of the troughs, by means of pulley blocks.

The drive for the crank rier may be on the carrier itself or may be firmly arranged on the support. In the first arrangement, a shaft, supplied with worms and running lengthwise to the yarn carrier, is driven by a motor at the end of the carrier. By means of worm-wheels on the shafts of the crank mechanism, these are rotated by the worms. The shaft with the worms, worm-wheels and the shafts of the crank mechanism may be carried oil-tight Within the carrier, that is in the form of a pipe. This arrangement is of special advantage when the carrier is double-sided and only one common trough is employed, as then no impurities can fall into the bath.

The drawing represents one form of the machine for the sake of example. In the drawing Fig. 1 is a side elevation with a longitudinal section of the trough,

Fig. 2 is a view from above,

Fig. 3 is a view of, the top-end of the trough, the carrier being raised,

Fig. 4 is the same view with into position,

form, both sides of the mechanism of the car- Fig. 5 is an enlarged detail view of the crank mechanism shown in Fig. 4.

At the ends of the trough a there are supports 1) with surfaces 0. On these surfaces, a carrier d with crank mechanism 1' may be placed. On the crank mechanism the frames m are suspended by means of the hanging devices 1. Threaded on sticks 12 small, adjustable reels 0, capable of expansion, are placed on the frames m.

A shaft f, provided with worms, is turned by a motor e. This shaft gives the crank shaft h a slow rotation by means of the worm-wheels g. In this manner, the crank mechanism i, It also receive a rotary motion and raise and lower the frames m by means of the hanging devices Z. In this way, spinning cakes 0 on the frames m are immersed in and lifted out of the bath again at regular intervals.

What I claim is I. A washing machine for artificial silk spinning cakes, comprising a trough, supports adjacent said trough, a carrier supported on and adapted to be lifted off said supports, said carrier being tube-formed, gearing situated within said tube-formed carrier, a crank operatively connected with the gearing, a frame for carrying a plurality of spinning cakes, and means to hang the frame on the crank.

2. Apparatus of the character described for washing filament masses, comprising a bath, a tubular member extending above the bath, means to support the tubular member, a shaft in the tubular member having a worm secured thereto, a gear in the tubular member for rotation by the worm, a shaft extending through the sides of the tubular member and secured to the gear, crank arms in generally vertical planes secured to the last-named shaft on opposite sides of the tubular member, means for supporting a plurality of said filament masses, and means for hanging the lastnamed means on the crank arms.
